Acclaim
“This blend, that balances crisp lemon against a more perfumed character from Monscatel, is attractively fresh and fruity. It is a vivacious wine, with fruit and acidity giving a fine lift.” –  (Best Buy) — Wine Enthusiast, Dec 2023

Wine Production

Upon arrival at the winery, the grapes are de-stemmed and gently crushed, followed by pre-fermentative maceration at low temperature for 12-24 hours. The grapes are then pressed and fermentation takes place at controlled temperature between 14ºC - 16ºC.
